This book aims at enhancing our understanding of these processes and stresses recent important developments in this very active area of research. The concise, state-of-the-art reviews cover recent advances in many fields important to the area of myocardial ischemia and reperfusion including physiology, pathology, pharmacology, biochemistry and molecular biology with reference to clinical relevance and applicability of these findings. Major areas which are highlighted include vascular mechanisms resulting in myocardial ischemia, cellular events in the ischemic, postinfarcted and reperfused myocardium as well as new exciting developments in cardiac protection that involve both novel pharmacological approaches as well as endogenous cardioprotective mechanisms such as preconditioning. Aimed at both the basic and clinical cardiovascular investigator, the book comprehensively reviews the rapid progress made in recent years in understanding the etiology of myocardial ischemia and reperfusion. It will further serve as an authoritative reference for all those interested in learning about the important developments in the treatment of myocardial ischemic and reperfusion disorders.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 532 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This book contains the refereed papers which were presented at the interna tional conference on 'Multivariate Approximation and Splines' held in Mannheim, Germany, on September 7-10,1996. Fifty experts from Bulgaria, England, France, Israel, Netherlands, Norway, Poland, Switzerland, Ukraine, USA and Germany participated in the symposium. It was the aim of the conference to give an overview of recent developments in multivariate approximation with special emphasis on spline methods. The field is characterized by rapidly developing branches such as approximation, data fit ting, interpolation, splines, radial basis functions, neural networks, computer aided design methods, subdivision algorithms and wavelets. The research has applications in areas like industrial production, visualization, pattern recognition, image and signal processing, cognitive systems and modeling in geology, physics, biology and medicine. In the following, we briefly describe the contents of the papers. Exact inequalities of Kolmogorov type which estimate the derivatives of mul the paper of BABENKO, KOFANovand tivariate periodic functions are derived in PICHUGOV. These inequalities are applied to the approximation of classes of mul tivariate periodic functions and to the approximation by quasi-polynomials. BAINOV, DISHLIEV and HRISTOVA investigate initial value problems for non linear impulse differential-difference equations which have many applications in simulating real processes. By applying iterative techniques, sequences of lower and upper solutions are constructed which converge to a solution of the initial value problem.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 340 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Arguably, many industrial optimization problems are of the multiobjective type. The present work, after providing a survey of the state of the art in multiobjective optimization, gives new insight into this important mathematical field by consequently taking up the viewpoint of differential geometry. This approach, unprecedented in the literature, very naturally results in a generalized homotopy method for multiobjective optimization which is theoretically well-founded and numerically efficient. The power of the new method is demonstrated by solving two real-life problems of industrial optimization.The book presents recent results obtained by the author and is aimed at mathematicians, scientists, students and practitioners interested in optimization and numerical homotopy methods.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 148 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -This volume contains a selection of invited papers, presented to the fourth In Statistical Analysis Based on the L1-Norm and Related ternational Conference on Methods, held in Neuchatel, Switzerland, from August 4-9, 2002. Organized jointly by the University of Illinois at Chicago (Gib Bassett), the Rutgers University (Regina Liu and Yehuda Vardi) and the University of Neuchatel (Yadolah Dodge), the conference brought together experts whose research deals with theory and ap plications involving the L1-Norm. The conference included invited and contributed talks as well as a tutorial on Quantile Regression. This volume includes 36 refereed invited papers under seven headings. Part one deals with Quantiles in all their forms and shapes. It includes papers on quantile functions in non-parametric multivariate analysis, and empirical applications of quantile regression. Much of the development in this direction follows from the fundamental paper by Koenker and Bassett in 1978. Financial and Time Series A nalysis follows the section on quantiles. Part three concerns Estimation, Testing and Characterization. Part four, Deep in the Data, deals with issues related to data depth. Part five addresses Classification questions. The problem of Density Estimation and Image Processing is discussed in Part six, and finally Part seven presents two environmental applications. The contributions represent clear evidence of important research involving theo retical issues and applications associated with the L1-Norm. It is my hope that the articles contained in this volume and its predecessors, published in 1987, 1992, and 1997, will stimulate interest among researchers.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 472 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -These two volumes constitute texts for graduate courses in linear operator theory. The reader is assumed to have a knowledge of both complex analysis and the first elements of operator theory. The texts are intended to concisely present a variety of classes of linear operators, each with its own character, theory, techniques and tools. For each of the classes, various differential and integral operators motivate or illustrate the main results. Although each class is treated seperately and the first impression may be that of many different theories, interconnections appear frequently and unexpectedly. The result is a beautiful, unified and powerful theory. The classes we have chosen are representatives of the principal important classes of operators, and we believe that these illustrate the richness of operator theory, both in its theoretical developments and in its applicants. Because we wanted the books to be of reasonable size, we were selective in the classes we chose and restricted our attention to the main features of the corresponding theories. However, these theories have been updated and enhanced by new developments, many of which appear here for the first time in an operator-theory text. In the selection of the material the taste and interest of the authors played an important role.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 572 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -An exploration of the theory of discrete integrable systems, with an emphasis on the following general problem: how to discretize one or several of independent variables in a given integrable system of differential equations, maintaining the integrability property This question (related in spirit to such a modern branch of numerical analysis as geometric integration) is treated in the book as an immanent part of the theory of integrable systems, also commonly termed as the theory of solitons. Most of the results are only available from recent journal publications, many of them are new.Thus, the book is a kind of encyclopedia on discrete integrable systems. It unifies the features of a research monograph and a handbook. It is supplied with an extensive bibliography and detailed bibliographic remarks at the end of each chapter. Largely self-contained, it will be accessible to graduate and post-graduate students as well as to researchers in the area of integrable dynamical systems.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 1124 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware - 1. Historical Remarks Convex Integration theory, first introduced by M. Gromov [17], is one of three general methods in immersion-theoretic topology for solving a broad range of problems in geometry and topology. The other methods are: (i) Removal of Singularities, introduced by M. Gromov and Y. Eliashberg [8]; (ii) the covering homotopy method which, following M. Gromov's thesis [16], is also referred to as the method of sheaves. The covering homotopy method is due originally to S. Smale [36] who proved a crucial covering homotopy result in order to solve the classification problem for immersions of spheres in Euclidean space. These general methods are not linearly related in the sense that succes sive methods subsumed the previous methods. Each method has its own distinct foundation, based on an independent geometrical or analytical insight. Conse quently, each method has a range of applications to problems in topology that are best suited to its particular insight. For example, a distinguishing feature of Convex Integration theory is that it applies to solve closed relations in jet spaces, including certain general classes of underdetermined non-linear systems of par tial differential equations. As a case of interest, the Nash-Kuiper Cl-isometrie immersion theorem ean be reformulated and proved using Convex Integration theory (cf. Gromov [18]). No such results on closed relations in jet spaees can be proved by means of the other two methods.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 228 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Allelochemicals play a great role in managed and natural ecosystems. Apart from plant growth, allelochemicals also may influence nutrient dynamics, mycorrhizae, soil chemical characteristics, and microbial ecology. Synergistic action of various factors may better explain plant growth and distribution in natural systems. The book emphasizes the role of allelochemicals in shaping the structure of plant communities in a broader ecological perspective. The book addresses the following questions: (1) How do allelochemicals influence different components of the ecosystem in terms of shaping community structure (2) Why is it difficult to demonstrate interference by allelochemicals (i.e., allelopathy) in a natural system in its entirety Despite a large amount of existing literature on allelopathy, why are ecologists still skeptical about the existence of allelopathy in nature (3) Why are there only scarce data on aquatic ecosystems (4) What role do allelochemicals play in microbial ecology .Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 288 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The human immune system, despite having its own sophisticated defence mecha nisms, is inferior to bacteria and viruses with respect to adaptability. Furthermore, our immune system is increasingly exposed to detrimental effects, that is immuno suppressive environmental consequences, unhealthy living, and chronic illnesses. Excessive chemotherapy threatens our immune system even further. This situation demands compensatory prophylactic therapeutic regimes. One of these - specific immunostimulation - is more difficult to achieve than the immunosuppression cur rently used in transplantation surgery and the medical treatment of autoimmune dis eases. The earliest attempts to develop suitable medication for immunostimulation were based on traditional remedies which embodied the accumulated experience of several centuries. Medicinal plants are already being used prophylactically as stan dardized and efficacy-optimized preparations for the treatment of various recur rent infections, or in combination with chemotherapeutics in standard medical practice. In order to rationally apply immunostimulants of plant origin, however, it is necessary to search for the active principles of these substances and to produce them in a pure form. Because suitable screening methods have become available only recently, research in this field is in its very beginning. Further progress can be expected from systematic basic research on the mechanisms underlying immunomodulation. This also applies to verification of clinical efficacy, which is a prerequisite for the acceptance of medications with purported immunostimulatory properties. 388 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lung cancer is a disease with pandemic public health implications as it is now the leading cause of cancer mortality throughout the world. This book results from two recent International Association for the Study of Lung Cancer (IASLC) Workshops on lung cancer prevention. It strikes a balance between considering public health approaches to tobacco control and population-based screening, advances in clinical evaluation of chemoprevention approaches, and the biology of lung carcinogenesis. Indeed, while the science of smoking cessation is evolving as new pharmacological tools are moving into clinical evaluation, the current impact of molecular diagnostics is profound. The rapidly-evolving diagnostic technologies are revolutionizing basic scientific investigation of cancer, and this trend is expected to soon spill over into the clinical practice of medicine. The evolution of economical diagnostic platforms to allow for direct bronchial epithelial evaluation in high-risk populations promises to improve the diagnostic lead-time for this disease. The hope is that enough progress will occur to permit lung cancer detection in advance of clinical cancer so that the disease can be addressed early on, while it is still confined to the site of origin. Chemoprevention, which is designed to intervene in the early phase of carcinogenesis prior to any subjective clinical manifestation of a cancer, is also generating greater research interest. Moreover, the benefit of aerosolized administration of chemoprevention agents over conventional oral administration has strong appeal and may result in the reduction of the incidence of cancer when combined with new diagnostic technologies. 348 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the Proceedings of the International Workshop Variational Methods For Discontinuous Structures, which was jointly organized by the Dipar timento di Matematica Francesco Brioschi of Milano Politecnico and the Interna tional School for Advanced Studies (SISSA) of Trieste. The Conference took place at Villa Erba Antica (Cernobbio) on the Lago di Como on July 4- 6, 2001. In past years the calculus of variations faced mainly the study of continuous structures, say particularly problems with smooth solutions. One of the deepest and more delicate problems was the regularity of weak solutions. More recently, new sophisticated tools have been introduced in order to study discontinuities: in many variational problems solutions develop singularities, and sometimes the most interesting part of a solution is the singularity itself. The conference intended to focus on recent developments in this direction. Some of the talks were devoted to differential or variational modelling of image segmentation, occlusion and textures synthesizing in image analysis, varia tional description of micro-magnetic materials, dimension reduction and structured deformations in elasticity and plasticity, phase transitions, irrigation and drainage, evolution of crystalline shapes; in most cases theoretical and numerical analysis of these models were provided. viii Preface Other talks were dedicated to specific problems of the calculus of variations: variational theory of weak or lower-dimensional structures, optimal transport prob lems with free Dirichlet regions, higher order variational problems, symmetrization in the BV framework. 204 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our goal is to find Grabner bases for polynomials in four different sets of expressions: 1 x- , (1 - x)-1 (RESOL) X, 1 x- (1 - xy)-1 (EB) X, , y-1, (1-yx)-1 y, (1_y)-1 (1-x)-1 (preNF) (EB) plus and (1 - xy)1/2 (1 - yx )1/2 (NF) (preNF) plus and Most formulas in the theory of the Nagy-Foias operator model [NF] are polynomials in these expressions where x = T and y = T\*. Complicated polynomials can often be simplified by applying 'replacement rules'. For example, the polynomial (1 - xy)-2 - 2xy(1-xy)-2 + xy2 (1 - xy)-2 -1 simplifies to O. This can be seen by three applications of the replacement rule (1-xy) -1 xy -t (1 - xy)-1 -1 which is true because of the definition of (1-xy)-1. A replacement rule consists of a left hand side (LHS) and a right hand side (RHS). The LHS will always be a monomial. The RHS will be a polynomial whose terms are 'simpler' (in a sense to be made precise) than the LHS. An expression is reduced by repeatedly replacing any occurrence of a LHS by the corresponding RHS. The monomials will be well-ordered, so the reduction procedure will terminate after finitely many steps. Our aim is to provide a list of substitution rules for the classes of expressions above. These rules, when implemented on a computer, provide an efficient automatic simplification process. We discuss and define the ordering on monomials later. 422 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Massively Parallel Systems (MPSs) with their scalable computation and storage space promises are becoming increasingly important for high-performance computing. The growing acceptance of MPSs in academia is clearly apparent. However, in industrial companies, their usage remains low. The programming of MPSs is still the big obstacle, and solving this software problem is sometimes referred to as one of the most challenging tasks of the 1990's. The 1994 working conference on 'Programming Environments for Massively Parallel Systems' was the latest event of the working group WG 10.3 of the International Federation for Information Processing (IFIP) in this field. It succeeded the 1992 conference in Edinburgh on 'Programming Environments for Parallel Computing'. The research and development work discussed at the conference addresses the entire spectrum of software problems including virtual machines which are less cumbersome to program; more convenient programming models; advanced programming languages, and especially more sophisticated programming tools; but also algorithms and applications. 423 pp. Englisch.

Freshwater environments often impose spatial structure on populations, e.g. within large lakes or among habitat patches, facilitating genetic and phenotypic divergence. Traditionally, freshwater systems have featured prominently in ecological research and population biology.This book brings together information on diverse freshwater taxa, with a mix of critical review, synthesis, and case studies. Using examples from bryozoans, rotifers, cladocerans, molluscs, teleosts and others, the authors cover current conceptual issues of evolutionary ecology in considerable depth.The book can serve as a source of critically evaluated ideas, detailed case studies, and open problems in the field of evolutionary ecology. It is recommended for students and researchers in ecology, limnology, population biology, and evolutionary biology. 384 pp. Englisch.
